Hello all,

This is a bus maintenance/terminal that pursues LEED v4 platinum. 85% of
the spaces in the proposed design have heating and ventilation system only
with no cooling. The remaining 15% of the spaces will be conditioned with
chilled beam, HW heating and DOAS with heat recovery. The HVAC system for
the baseline case is System 7 per ASHRAE table G3.1.1A.

What is the appropriate system for the heating ventilating spaces in both
of the models? Should I assume cooling system identical to System 7 with
high cooling temperature per Table G3.1.10 or I can assume as designed
system for the proposed model and system 9 for the baseline case?

As usual, thank you for your help.

Morteza
